Yen Nears Post-Intervention Levels as USD/JPY Falls to 155.7
The Yen has gained 2.6% this week against the Dollar, pushing USD/JPY down to around 155.7-155.8 and within striking distance of the 155.2 level hit after Tokyo and Washington’s joint intervention in late July. markets are pricing in a Bank of Japan rate hikeMarkets now imply a 75% chance of a Bank of Japan hike this month, with a further move by October fully priced in, keeping intervention risk alive on any sharp bounce.
ForexWaller Cuts September Hike Odds to 50%, Dollar Index Near 98.96
Fed Governor Christopher Waller said recent data suggest disinflation is finally emerging and that he would favour a hold this month if the trend continues, in remarks made for a Reuters NEXT Newsmaker event. Futures cut the odds of a September hike to about 50% from roughly 63% a day earlier, pulling the Dollar index down to near 98.96 and set for a 0.7% weekly loss.
RatesKOSPI Jumps Over 1.3% as Samsung and SK Hynix Lead a Foreign-Buying Return
The KOSPI opened 1.14% higher at 6,654.36 and extended gains toward 6,682, up as much as 1.6% from Thursday’s 6,579.48 close, as foreign and institutional investors bought together for the first time in six sessions. Semiconductor and IT shares are leading, while some financial, battery and insurance names lag behind the broader advance.
EquitiesCopper Holds Near Record High on Chile Supply Strain and Acid Shortage
Copper futures are trading near $6.58 a pound, just below August’s all-time high of $6.83, up more than 46% year-on-year. Persistent output declines at Chile’s Codelco and a sulfuric-acid shortage tied to disrupted Middle East shipping continue to strain refiners, even as elevated bond yields periodically cap the advance.
CommoditiesWheat Holds Near Three-Year High as Black Sea Risk Premium Persists
Chicago wheat futures are trading near $7.72-7.75 a bushel, close to the highest levels since early 2023, up roughly 45% year-on-year, after reports that Moscow rejected the latest ceasefire proposal reinforced the Black Sea war-risk premium that has underpinned the grain complex for weeks.
CommoditiesCrypto Majors Rally as Bitcoin Reclaims $80,000, Solana and Cardano Jump
Bitcoin has climbed back above $80,000 as the same rate-relief trade lifting equities eases the yield pressure that had weighed on crypto through the week. Solana is up about 4% near $103.50-104, while Cardano has jumped roughly 7-12% in 24 hours toward $0.221, additionally helped by a governance-renewal vote clearing key thresholds.

Asian Session Overview
“Waller is pushing back against the thrust of the argument made by Warsh last week that there is little evidence that underlying inflation has moved lower.” — JPMorgan analyst note, cited by Reuters
Asian shares are climbing on Friday as investors embrace a global rally ahead of crucial US jobs data, while bonds found some relief after Fed Governor Christopher Waller’s dovish remarks cooled rate-hike fears and dragged the Dollar lower. The Dollar’s retreat has turbocharged the Yen, which has gained 2.6% this week to trade near 155.7-155.8 against the greenback, putting it within reach of the 155.2 level struck after the joint Tokyo-Washington intervention in late July.
Two-year Treasury yields are holding near 4.34% after falling from a 20-month peak, while ten-year yields sit little changed near 4.76% and thirty-year yields near 5.24%. Investors in longer-dated bonds remain wary of inflation risk given scant progress between the US and Iran on ending the Gulf conflict; Brent crude is up around 7% this week near $95.50 a barrel. Gold is holding near $4,470-4,490 an ounce after a 2% overnight rally, though it is on course to finish the week little changed.

Asian Session Trade Ideas — USD/JPY, KOSPI, Copper and More
Technical setups and fundamental context across the session’s seven key instruments
USD/JPY
Why This Setup
The pair is being squeezed by two reinforcing forces: Waller’s dovish tilt has knocked the Dollar broadly lower, while hawkish Bank of Japan repricing has markets pricing a 75% chance of a hike in two weeks and a further move fully priced by October. USD/JPY is now within a whisker of the 155.2 level struck during July’s joint Tokyo-Washington intervention, and Vice Finance Minister Mimura’s repeated warnings that authorities are “neither satisfied nor reassured” keep the risk of fresh official action alive on any sharp bounce. The main two-way risk is a hot US payrolls print later today, which would likely stall the Dollar’s slide and could spark a sizeable short-covering rally back above 157.
AUD/JPY
Why This Setup
This is almost entirely a Yen story. The Reserve Bank of Australia remains hawkish after hot inflation and a strong second-quarter GDP print, which would normally support AUD crosses, but broad Yen strength tied to hawkish Bank of Japan repricing is dominating the pair and pushing it toward the 111 handle. Classic carry-trade-unwind dynamics argue for further downside if BoJ hike bets keep firming or if intervention is confirmed, since investors financing AUD longs with cheap Yen would be forced to unwind. A dovish surprise from the BoJ or a much weaker-than-expected US payrolls print, which would cap the Yen’s advance, are the main sources of two-way risk.
Copper
Why This Setup
Copper remains underpinned by genuine supply-side stress: Chile’s Codelco continues to report declining output from aging mines, and disrupted Middle East shipping has triggered a shortage of sulfuric acid, a key refining input, adding fresh pressure on top of already-tight inventories. That has kept the metal within reach of August’s record $6.83 high even as long-dated bond yields near multi-year peaks periodically weigh on the broader industrial-metals complex by raising financing costs and clouding the manufacturing outlook. A weak payrolls print today, which would ease yields further, is a tailwind; a resumption of the bond-yield surge is the main two-way risk.
Wheat
Why This Setup
Chicago wheat is holding near its highest levels since early 2023 after reports that Moscow rejected the latest ceasefire proposal reinforced the Black Sea war-risk premium that has driven a roughly 14% one-month rally. Russia and Ukraine together account for more than a quarter of global wheat exports, and continued attacks on commercial shipping keep supply disruption front of mind for traders. Technical readings on the Kansas City contract point to overbought conditions after a sharp run higher, so a near-term pullback toward the $7.50 area would not be surprising before the next leg, while a resolution of Black Sea shipping risk is the main downside catalyst.
KOSPI
Why This Setup
The index opened 1.14% higher at 6,654.36 and pushed as high as roughly 6,682 as foreign and institutional investors bought together for the first time in six sessions, easing worries about a US rate increase after Waller’s remarks. Samsung Electronics and SK Hynix are the biggest contributors to the advance, tracking the same AI and semiconductor-led leadership seen on Wall Street, though the rally is not fully broad-based, with some financial, battery and insurance names lagging. A hot payrolls print that revives September hike bets is the main risk to the rally holding into the New York open.
Cardano (ADA)
Why This Setup
ADA is riding the same rate-relief wave lifting Bitcoin and equities, with easing Fed hike odds reducing the yield headwind that had capped crypto through the week, but the sharpest driver today is idiosyncratic: a Cardano governance-renewal vote has cleared key thresholds, adding a fundamental catalyst on top of the macro tailwind. The move has been accompanied by a meaningful jump in trading volume, a healthy sign for the rally’s durability, though ADA remains more than 90% below its 2021 all-time high and prone to sharp reversals. A broad crypto risk-off move triggered by a hot payrolls print is the main source of two-way risk.
Solana (SOL)
Why This Setup
SOL is extending a sharp rebound that has taken it more than 40% higher over the past month, supported by continued spot-ETF inflows, strong network-activity data and the same broad crypto risk-on move tied to falling Fed hike odds. The token has cleared the $100 psychological level and is consolidating in the high-$90s-to-mid-$100s range, with bulls and bears still taking turns in control on shorter timeframes according to recent trading commentary. Large-holder positioning and well-known market makers’ short exposure have been flagged as a source of intermittent spot pressure, alongside the same payrolls-driven macro risk facing every instrument in this report.

Asian Session Summary — Friday, 4 September 2026 (Live Update)
Friday’s Asian session is trading firmly higher as investors extend Thursday’s Wall Street rally into the crucial US jobs report. Fed Governor Christopher Waller’s remark that recent data show signs of disinflation and that he would favour a September hold cut futures-implied hike odds to about 50% from roughly 63% a day earlier, dragging the Dollar index down to near 98.96-99.26 and driving MSCI’s broadest Asia-Pacific index excluding Japan up around 1% on the day, even as the gauge remains roughly 0.4% lower for the week.
The Yen is the standout mover, with USD/JPY sliding to about 155.7-155.8, down 2.6% this week and within reach of the 155.2 level struck during July’s joint Tokyo-Washington intervention, as markets now imply a 75% chance of a Bank of Japan hike in two weeks. That Yen strength is dominating carry-sensitive crosses such as AUD/JPY, which has slipped toward 111-112 even though the Reserve Bank of Australia remains hawkish on its own merits. South Korea’s KOSPI has jumped as much as 1.6% to the 6,660-6,680 area as foreign and institutional investors return to buying Samsung Electronics and SK Hynix, tracking the same semiconductor-led leadership seen on Wall Street.
Commodities are holding firm on their own supply stories: Copper near $6.58 a pound is within reach of August’s record high on Chilean output declines and a Middle East-linked sulfuric-acid shortage, while Wheat near $7.72-7.75 a bushel sits at its best levels since early 2023 on Black Sea war-risk premium. Crypto majors are firmly bid alongside the broader risk rally, with Cardano up sharply near $0.221 on a governance-vote catalyst and Solana extending a one-month rebound near $103.50-104 as Bitcoin reclaims $80,000.
Highest-conviction session idea: fade the Yen crosses — selling rallies in USD/JPY and AUD/JPY — while buying dips in KOSPI, Copper, Wheat and the crypto majors on the same rate-relief theme, and staying alert to today’s Non-Farm Payrolls, which lands after the Asian close but can reverse every one of these positions once New York trading begins.
For the individual instruments: USD/JPY sell rallies toward 157.20, stop 158.60, target 153.00 — hawkish BoJ repricing and a softer Dollar are a genuine tailwind, though a hot payrolls print is a real source of two-way risk. AUD/JPY sell rallies toward 112.80, stop 113.80, target 109.00 — broad Yen strength is a genuine tailwind for the downside case, though a hawkish RBA is a real source of two-way risk. Copper buy dips toward $6.40, stop $6.20, target $6.85 — Chilean supply strain and the acid shortage are a genuine tailwind, though a bond-yield resurgence is a real source of two-way risk. Wheat buy dips toward $7.50, stop $7.30, target $8.10 — Black Sea war-risk premium is a genuine tailwind, though overbought technicals are a real source of two-way risk. KOSPI buy dips toward 6,580, stop 6,480, target 6,850 — returning foreign flows and chip-stock strength are a genuine tailwind, though a hot payrolls print is a real source of two-way risk. Cardano buy dips toward $0.205, stop $0.185, target $0.260 — the governance-vote catalyst and falling hike odds are a genuine tailwind, though crypto’s volatility is a real source of two-way risk. Solana buy dips toward $97.50, stop $91.00, target $118.00 — ETF inflows and network growth are a genuine tailwind, though large-holder positioning is a real source of two-way risk. The decisive variable for the rest of the day is whether this rate-relief, risk-on, Yen-strength narrative survives contact with tonight’s Non-Farm Payrolls, so size positions accordingly and note that fast-moving intervention headlines and geopolitical developments carry genuine event risk that could exaggerate moves in either direction.
